If you don't mind me asking, why do you think Hubski has failed so far? You'd think its innovation really would make it a likely candidate for passing the network effect threshold.

I think part of it is the personal nature of the discussion. It is full of intelligent, successful people who tend to think for themselves and do lots of interesting things outside of the internet. It can be intimidating and can make one worry they might be judged for commenting. Especially because some of the big names around there can be a bit touchy if you say something they don't like.

I think another reason is because Hubski sucks and is full of spammers when you're not logged in. You need to log in to get the full benefit and curation.

What is hubski's innovation? Using tags to organize more prolifically?
